MERRITT GALLY, on NEW YORK, N. Y.

MECHANICAL MUSICAL INSTRUMENT.

SPECHICATION forming part of Letters Patent No. 331,747, dated December 1, 1885.

Application filed July U, 1884. Serial No. 137,391. (No model.)

To all whom; it may concern: 'Be it known that I, MERRITT GALLY, a citizen of the United States, residing in the city of New York, county of New York, and State of New York, have invented new and usefulIn'nprovements in Musical Instruments, of which the following is a specification. In the accompanying drawings, Figure 1 is a transversesectional view of an organ-action embodying my invention, showing a number} of parts and their combinations, and Fig. 2 is a detached view of the combined stop and yalve apparatus of the action, which are out awayin Fig. 1.

In pipe-organs, in which the length of the range of the pipes is usually much longer than the length of the manual key-board, pneumatic actions operated by means of the manual are quite common; but iureed-organs, in which the reeds may all be placed within a space no larger than the manual, the construction is confined to push-'pins,being much cheaper than radiating pneumatic tubes.

There would be advantages gained by the use of pneumatic actions in reed-organs operated ouly'by manuals, provided cheap construction could be secured, as the keys of the manual would be more easily operated and the movement of the valves more sensitive. The advantages are greater when the instrument is to be operated by means of the manual or mechanically at will.

The drawings show a construction which provides a simple and eifective pneumatic action, so constructed and arranged as to lie, when desirable, entirely within the range of the manual, requiring no radiating tubes for the manual-connections. This action may be used equally well for either an organ operated by manual only or for an organ operated mechanically, or operated mechanically or manually.

Fig. 1 represents an organ provided with three full ranges of reeds, the reed-boards V V containing one range, the reed-boards R R containing another range, and the reed-boards X X containing a third range. The pairs of reed-boards, as V V, contain the reeds of the scale arranged alternating in their progression from one board to the other, so that each valveboard has the space of two finger-keys to each reed of its reed-board, to accommodate the pneumatic motor, and still the entire range of reed is brought within the range of the manual.

The pneumatic motors and sounding-valves, when constructed as shown and contained within the air-chest, as A, are similar in most respects to those I have already described in former specifications. Their arrangement differs in that one half of the action is in ordinary position,while the other half is inverted, or placed facing the other. The line of the vent-tubes which operate the pneumatic motors for the valves of the set of reeds V V are stopped off by the line of'operating-valves 1. The ducts from these valves alternately lead to the motors of the upper and lower part of the action, the ducts for the lower part of the action passing down through the partition N, as shown by the dotted lines. The valves for the sets of reeds R It and X X are operated in similar manner by means of the lines of operating-valves 2 and 8. It will be seen that each set is independent in itself, and is operated by its independent line of operatingvalves. This obviates the necessity of using mutes or other ordinary stops. To stop off any set, it is only necessary to render inoperative its set of pneumatics.

The operating vent-valves 1 2 3 are operated by means of the lifting-hooks a ef, which are pivoted to the lifting bar or lever D, said hooks and lever constituting the valve-lifter. One end of the bar D connects with the fingerkey K, and if the instrument is intended to be operated mechanically or automatically the other end of bar D connects with an automatic or mechanically-operated pneumatic motor, T, connecting through tube P with the trackerrange T and music-sheet S The trackerrange is shown providing for the connection of one half the range of tubes on one side of the tracker T. The other half of the range of tubes connect with the opposite side of the tracker T, and therefore are not in view in the drawings.

To render inoperative any one of the three ranges of the organ, I simply render inoperative its line of hooks a, e, or f, as the case may be. For this purpose I provide each line of hooks with a pivoted eccentric-rod, z, which,

being turned on its pivot, throws the books out of range of the vent-valves, as shown by the dotted lines at a.

In order to render different parts of any range inoperative independently of the other parts, I divide the eccentricrod, as to its length, into any number of parts desirable, operating each part separately. The operating devices for this stop action are shown in Fig. 2, being cut away by the section in Fig. 1.

Two means for the movement of eccentricrod 2 are shown in Fig. 2. one for operating by hand in connection with the manual keyboard, and the other to act-pneumatically in connection with the automatic action. From each side of the eccentric-rod 2 projects a lever, to which are connected the pneumatics n and m, one to throw the stop on, the other to throw it off. These pneumatics are to operate in connection with the automatic action.

For operating the stops by hand, I either connect the pneumatics n and m with fingerkeys or use the cam L, connected to an ordinary draw-stop. A pin projecting from the side of the tilting-lever of eccentric-rod z operates in the cam. The cam, having a reciprocating movement, operates the lever. The ends of the cam are open, so that whether the draw-stopis out or in the pneumatics can act freely on the levers. The bellows E F G con nect with chambers A B O, and also with the pneumatic action T. The manual-key K lifts one end of bar D. The pneumatic T lifts the opposite end of bar D. The operation of the instrument is the same, either end of the bar being lifted.

To limit the movement of the valve-levers in the chests A B O, I usually employ a rightangle wire hanger projecting from the Valve board, with a set-screw and button screwing into the lever for limiting the movement, the button striking the right-angle projection of the Wire hanger. In the present case I show only a right-angle wire hanger. A screwthread is cut on the end of this hanger, so that it can be screwed more or less into the valveboard. This forms a simple and cheap stop for the purpose, and is much cheaper than the other construction. The actions are placed either horizontal or vertical, as shown.

What I claim as my invention is 1. In an organ action, two valveboards facing each other and provided with pneumatic valves alternately leading to the two valveboards.

2. The bar or lever, as D, provided with lifting-hooks, as a e f, for operating different sets of vent-valves, substantially as specified.

3. The combination, with the vent-valves, as 1 2 3, of the manual-key Kand the operating lever and hooks, substantially as specified.

4. The combination, with the vent-valves, as l 2 3, of the lever D, provided with its operating-hooks, and a pncu matic motor, as T, substantially as specified.

5. The combination, with the pneumatic vent-valve, as 1, of the operating lifting-hook and a device for throwing the hook out of operating connection with the valve, substantially as specified.

6. The combination, with a series of lifting hooks for operating pneumatic vent-valves, of the cammed rock -shaft z, substantially as set forth.

7. The combination, with a series of lifting hooks for operating a series of pneumatic vent-valves, of the cam rock-shaft z, operated by means of pneumatics, as n and m, substantially as specified.

8. The combination, with the series of valve-operating hooks and devices for throwing the hooks out of connection with the valves, of a hand draw-stop for operating the throwoff.

9. The combination, with the cammed rockshaft 2 and its lever projections, of the reciprocating cam L, substantially as and for the purpose specified.

10. The combination, with a vent-valve and a single lifter for the same, of a manual-key and a pneumatic motor, both operating on the lifter.

11. The combination, with a vent-valve and a lifter for the same, of a manual-key operating on one end of said litter, and apneumatic motor operating on the other end thereof.
